1 Claim.

The present invention relates in general to an improved hinge structure,and relates more specifically to improvements in the construction andoperation of a detachable hinge which is especially applicable toswinging windows, doors or the like.

Generally stated, an object of the invention is to provide an improvedhinge which is simplein construction and efficient in operation.

Some of the more specific objects of the invention are as follows:

To provide an improved hinge structure which is especially applicable toswinging windows, doors or similar closures.

To provide a hinge construction wherein the fixed and movable elementsmay be readily and quickly detached or assembled.

To provide a hinge which is light but strong in construction, and allparts of which may be manufactured at minimum cost.

To provide a hinge assemblage, the various elements of which areinterchangeable with similar parts of other assemblages, and which maybe conveniently applied to a swinging closureand its supporting frame.To provide a hinge structure which is compactin construction; and whichpresents a neat and pleasing appearance.

To provide improved mechanism cooperable with a hinge supported closure,for maintaining the hinge and closure in various positions ofadjustment.

These and other objects and advantages will be apparent from thefollowing detailed description.

A clear conception of several embodiments of the invention and of themode of constructing and of mainipulating hinge structures in accordancetherewith, may be had by referring, to the draw- 4.0: ing accompanyingand forming a part of this specification, in which like referencecharacters designate the same or similar parts in the various views.

Fig. 2 is a vertical section through the assemblage of Fig. l, thesection being taken on the line 2-2 of Fig. l and the hinges having beenomitted;

fragment of the assemblage of Fig. 1, showing the details ofconstruction of one of the improved hinges;

Fig. 5 is a similarly enlarged vertical section through the fragment andhinge of Fig. 4, the section being taken along the line 5-5 of Fig. 4;

Fig. 6 is an enlarged inside view of a fragment of the assemblage ofFig. 1, showing the details of construction of the closure latch, theview being'taken on the line 66 of Fig. 2;

' Fig. 7 is a. further enlarged horizontal section through the latchstructure of Fig. 6, the section being'taken along the line '7-7 of Fig.6; and I Fig. 8 is a fragment of a Window and supporting casing, showinga modified construction used as a window hanger. i i 7 Referring toFigs. 1 to '7 inclusive of the drawing the improved hinge has been shownas applied to the side of an ordinary casement window or screen in orderto swingably support the same. Each of the improved hinges comprises ingeneral a bracket 10 adapted for attachment to the casing 11 by means ofscrews 12 or the like; a hinge element '13 adapted for attachment to thescreen or window frame 14 by means of screws 15 and having'a tubularportion 16 provided with end openings which are alinable with sockets1'7 formed in the bracket 10; and an axially movable pivot 18 disposedwithin the tubular portion 16 of theelement 13 and having end portionsmovable into the sockets 17 of the bracket 10 to form a hinge connectionbetween the bracket 10 and the element 13. Each pivot 18 is resilientlyrestrained against movement within the tubular portion 16, by means of aleaf spring 19, and is provided with a lateral recess 20 adapted toreceive the swinging end of an arm 21. Each of the arms 21 is attachedto the outer end of a pivot pin 22 by means of a clamping screw 23, andthe pivot pin 22 is rotatably supported in a bore in the frame 14 andhas its inner end provided with an adjusting handle 24.

In the horizontally swingable casement type of window, it is preferableto utilize two or more of the improved hinges associated with one of theside edges of the closure, and the opposite edge of the window frame maybe provided with a locking or holding latch associated with the insideof the frame and casing, as shown in Figs. 1,

2, 3, 6 and 7. This latch comprises a latch bar 25 swingably supportedupon the frame 14 by 05 means of a pivot bracket 26 and having anintegral tongue 27 adapted to engage the adjacent portion of the casing11 to retain the window in closed position as shown in Figs. 6 and 7.The swinging portion of the bar 25 has a through pleting the hingeconnections.

opening 28 cooperable with a spring clip 29 in order to retain the barin locking position. The edge of the bar 25 may also be provided withone or more notches which are engageable with a grooved stop pin 31secured to the casing 11, when the window is swung open and the latchbar 25 is disposed horizontally, as shown in Figs.

'2 and 3, to thereby hold the window open to any desired extent.

In the modified form of hinge or hanger shown in Fig. 8, the bracket 32is of single construction and is secured to the casing 11 above thewindow frame 14. The hinge element 13 and the parts. associatedtherewith are identical with the corresponding structure previouslydescribed, and this modified device can be used advantageously in placeof the ordinary storm Window and screen hangers which present numerousobstacles; when it is attempted to hang such closures from the inside.

Inorder to. assemble a frame is and casing. 11. having the improvedhinges applied thereto, it is. only necessary to set the. pivots 18. bymanipulation of the handles 24:,v so thatv the ends. of the. pivots donot project, from the, ends of thetubular IlQrtions 16 of the confining,elements 13. The springs 19. will retain thev pivots. 18 within thetubular portions 16 until the frame 14; is positioned' within theopening in the casing. 11 with the openings of the tubular portions 16.in. alinement With the sockets 17 of the adjacent bracketsv 10. The.handles 24 may then be manipulated to move the pivots 18. axially withinthe. tubular portions 16 until the pivot. ends. enter the adjacentsockets, as shown in Figs. 1, 4 and 8, thereby com- The windows orscreens may be subsequently swung. about the pins 18 as pivots,. andwith the latch. applied, may be retained in open or, closed. position.The hinge connection may obviously be readily released by manipulatingthe handles 24. from within the C SHIe, and. these handles may be set atany zlesirectposition.v relative to the arms 21 by means of the clampingscrews 23.

It will thus be noted that the invention pro vides a simple, compactandhighly eiiicient hinge and; latch structure which may be readily apeplied and manipulated. The brackets 10, 26,. 3.2,. the elements 13, thelatchbars-25, and the spring, clips 29 may be readily formed of sheetmetal. with the aidof punches and dies, thereby reducing the cost ofconstruction thereof to a minimum and permitting interchangeability ofthese parts. While the pivots 18 when used in connection with the doublebrackets 10, may be shifted axially in either direction in order tocomplete the hinge connection, the double brackets 10 may be replaced bysingle brackets 32 whenever desired. The. improved latch mechanism mayor may not be used in conjunction with the. improved hinge structure andhas been found extremely efiective in actual use.

It will be noted that the angular disposition of thebracket 26 whichsupports the latch bar 25, causes this bar to swing clear of the casingwhen the bar is swung about its pivot, thereby avoiding, obstruction tothe opening and closing of the window or screen frame 14. The latch bar25 however, serveslto effectively retain the window or screen in closedposition when the end of the bar has been brought into lockingengagement. with the clip 29.. The formation of this latch bar and thepivotal mounting thereof, constitutev an important feature of thepresent. invention.

It should be-understoodthat. it is-not desired to. 100 limit theinvention to the exact details of con struction herein shown anddescribed, for various modifications within the scope of the claim. mayoccur to persons skilled in the art.

It is claimed and desired to. secure by Letters Patent:

In combination,.a socketed bracket. and an element. formed forattachment respectively to the exterior of a one-piece cooperatingcasingand window frame,.a pivot carried by said element and 1 0 cooperable.with the socket of said bracket. to form a hinge connectionv betweenthecasingv and frame, and an. arm having oneend. operatively connected withsaid. pivot. and. having its other end extended rotatably through. theframe-and 15 shaped to. provide a lifting. handle on the inside of said.frame, said.v handle having a: part spaced a sufficient distance fromthe. frame to provide for insertion of the, fingers betweenthev handlevand frame when the frame is being lifted into 1-20 position and. thehandle being turnable without changing; the. position of the fingers tooperate the pivot to move the latter. into; and out. of the socket.
